Vagrant external inventory script. Automatically finds the IP of the booted vagrant vm(s), and
|

returns it under the host group 'vagrant'
|
|
|
|
Example Vagrant configuration using this script:
|
|
|
|
config.vm.provision :ansible do |ansible|
|
|
ansible.playbook = "./provision/your_playbook.yml"
|
|
ansible.inventory_file = "./provision/inventory/vagrant.py"
|
|
ansible.verbose = true
